immunization

immunization

[im″u-nĭ-za´shun]

the process of rendering a subject immune, or of becoming immune. Called also inoculation and vaccination. The word vaccine originally referred to the substance used to immunize against smallpox, the first immunization developed. Now, however, the term is used for any preparation used in active immunization.

The Centers for Disease Control and Prevention has an Advisory Committee on Immunization Practice that reviews childhood immunization schedules yearly. The recommended childhood immunization schedule is reprinted in Appendix 7-1. In Canada, the Health Protection Branch Laboratory Center for Disease Control, Health Canada, National Advisory Committee on Immunization publishes a recommended childhood vaccination schedule for Canada (reprinted in Appendix 7-3). Adult immunization schedules for the United States and Canada are found in Appendices 7-2 and 7-4.

active immunization stimulation with a specific antigen to promote antibody formation in the body. The antigenic substance may be in one of four forms: (1) dead bacteria, as in typhoid fever immunization; (2) dead viruses, as in the Salk poliomyelitis injection; (3) live attenuated virus, e.g., smallpox vaccine and Sabin polio vaccine (taken orally); and (4) toxoids, altered forms of toxins produced by bacteria, as in immunization against tetanus and diphtheria.

Since active immunization induces the body to produce its own antibodies and to go on producing them, protection against disease will last several years, in some cases for life.

Active immunization is not without risks, although research supports the efficacy of immunization programs as a measure to reduce the incidence of infectious disease. Paradoxically, the more successful an immunization program and the higher the immunization rate, the more likely it becomes that a vaccine will cause more illness and injury than its target disease. Thus the risk of disease is less threatening than the risk of an adverse reaction to the vaccine that will prevent it.

In an effort to immunize larger numbers of children against preventable infectious diseases public health officials and health care professionals in the 50 states, the District of Columbia, Puerto Rico, the Virgin Islands, and Guam now enforce laws requiring children to be immunized before they enter school. Those children who come to school with incomplete or nonexistent records of immunizations are refused admittance until they are immunized.

Because of their potential for triggering anaphylaxis in hypersensitive persons, all immunizing agents should be given with caution and only after a health history has been completed on the patient. Emergency equipment and drugs should be readily at hand in all clinics and other facilities where immunizing agents are administered.

passive immunization transient immunization produced by the introduction into the system of pre-formed antibody or specifically sensitized lymphoid cells. The person immunized is protected only as long as these antibodies remain in his blood and are active—usually from 4 to 6 weeks.

immunization

[im′yənīzā′shən]

Etymology: L, immunis, free

1 a process that increases an organism's reaction to an antigen, thereby improving the organism's ability to resist or overcome infection. See also vaccination.

2 a technique used to induce an immune response to a specific disease in humans by exposing the individual to an antigen in order to raise antibodies to that antigen.

immunization/vaccination management

a nursing intervention from the Nursing Interventions Classification (NIC) defined as monitoring immunization status, facilitating access to immunizations, and providing immunizations to prevent communicable disease. See also Nursing Interventions Classification.

immunization

Immunology The process of inducing immunity by administering an antigen to allow the immune system to prevent infection or illness when it subsequently encounters the same pathogen. See Adult immunization, Alloimmunization, Anthrax immunization, Childhood immunization, Intracellular immunization, Passive immunization, Vaccination.

im·mu·ni·za·tion

(im'yū-nī-zā'shŭn)

Protection of susceptible individuals from communicable diseases by administration of a living modified agent, a suspension of killed organisms, or an inactivated toxin. See also: vaccination

immunization

The process of conferring a degree of protection or IMMUNITY against infection or the effects of infection. The terms ‘immunization’ and ‘vaccination’ are interchangeable. See also INOCULATION.

immunization

the administration of an ANTIGEN, in the form of a vaccine, to produce an IMMUNE RESPONSE to that antigen and so protect against future exposure to the antigen. see ATTENUATION.

Immunization

A process or procedure that protects the body against an infectious disease. A vaccination is a type of immunization.

immunization,

n defense against contagious illnesses acquired either through contact with the contagion or a less virulent form of it as through vaccination. See also immunotherapy and vaccinosis.

im·mu·ni·za·tion

(im'yū-nī-zā'shŭn)

Protection of susceptible patients from communicable diseases by administration of a living modified agent, suspension of killed organisms, a protein expressed in a heterologous organism, or an inactivated toxin.

immunization (vaccination) (im´ū-nəzā´shən),

n.pl1. a process by which resistance to an infectious disease is induced or augmented. 2. a fundamental element of preventative health care for dental workers, who should be fully immunized against influenza, hepatitis B, and all childhood diseases where a vaccine is available. See also immunity, active. HIV and hepatitis C vaccines are not available.

immunization

the process of rendering a subject immune, or of becoming immune. See also vaccination.

active immunization

stimulation with a specific antigen to promote an immune response. In the context of infectious diseases, the antigenic substances may include: (1) inactivated bacteria, as in botulism immunization; (2) inactivated viruses, as in the canine parvovirus vaccination; (3) live attenuated viruses, e.g. rabies virus, and (4) toxoids, chemically treated toxins produced by bacteria, as in immunization against tetanus and pasteurellosis. Any of a vast number of foreign substances may induce an active immune response.

Since active immunization induces the body to produce its own antibodies and specifically reactive cells and to go on producing them, protection against disease will last several years, in some cases for life.

antihormone immunization

immunization against hormones, e.g. against androstenedione for the stimulation of ovulation in ewes, is now a commercial reality and promises to be a significant management tool in intensive animal production. See also immunological contraception.

deliberate immunization

the administration of an immunogen, usually by injection but sometimes orally or by inhalation, for the purpose of producing immunity.

natural immunization

stimulation of the immune system through exposure to antigens that have not been deliberately administered.

passive immunization

transient immunization produced by the introduction into the system of pre-formed antibody or specifically reactive lymphoid cells. The animal immunized is protected only as long as these antibodies or cells remain in the blood and are active—usually from 4 to 6 weeks. The immunity may be natural, as in the transfer of maternal antibody to offspring, or artificial, passive immunity following inoculation of antibodies or immune cells.

Patient discussion about immunization

Q. Is there a vaccination against hepatitis? I want to volunteer in a charity organization abroad soon, and I heard that currently there’s and outbreak of hepatitis in the town I intend to go to. Is there anything I can do to prevent me from getting hepatitis? Is there a way to get a vaccination against it?

A. before you would like to go on with any vaccination, you should check out this very long list of links:

http://www.aegis.ch/neu/links.html

at the bottom you will also find links in english. vaccinations in general are very disputable/dubious and it is probably time that we learn about it.

Q. Why does the body attack itself in autoimmune diseases? And if it’s possible - How come it doesn’t happen most of the time?

A. Some say cell-wall deficient (CWD) bacteria can live inside your cells (were apparently photographed in immune cells under electron microscope). See www.marshallprotocol.com and autoimmunityresearch.org (run by the autoimmunity research foundation). Also see bacteriality.com. I have been on the MP for just over a year. It has helped a lot of my symptoms, including lowering my TSH (thyroid) from hashimoto's thyroiditis (autoimmune thyroid condition). I hope that my thyroid will eventually regain all of it's function (still taking some thyroid hormone supplement, but less). The MP is not without "side effects," which are said to be from bacterial die-off and cell death when the bacteria are killed. It is experimental and should only be undertaken with that in mind. The marshallprotocol.com website is currently moderated by volunteers. There needs to be more research on CWD bacterial colonies and their possible role in autoimmune diseases. Please mention this to your doctor(s).
